Book 3 of 39 in the Old Testament — Holiness & worship.
Leviticus functions as a manual for the newly freed nation, detailing the sacrifices, festivals, and purity laws that would govern Israel's worship. Much of the book addresses how a sinful people can approach a holy God without being destroyed by his presence. Instructions for priests sit alongside rules for everyday life — diet, disease, relationships — all aimed at marking Israel as distinct among the nations. Its central refrain, ‘be holy, for I am holy,’ summarizes its purpose.
“For I am the LORD your God: ye shall therefore sanctify yourselves, and ye shall be holy; for I am holy: neither shall ye defile yourselves with any manner of creeping thing that creepeth upon the earth.”King James Version
God calls Israel to be holy because he is holy.
“For on that day shall the priest make an atonement for you, to cleanse you, that ye may be clean from all your sins before the LORD.”King James Version
The Day of Atonement provides yearly cleansing from sin for the whole nation.
“Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the LORD.”King James Version
The command to love your neighbor as yourself, later quoted by Jesus as a summary commandment.
“Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; ye shall do no work therein: it is the sabbath of the LORD in all your dwellings.”King James Version
The Sabbath is established as a permanent day of rest for God's people.
“And I will walk among you, and will be your God, and ye shall be my people.”King James Version
God promises to walk among his people and be their God.
